AutoCAD Inventor :: Replace Assembly With Its Subassembly Without Losing Constraint?
Nov 24, 2011
I have an Assembly2 in Assembly1. I'd like to insert Assembly2 to Assembly 3 without losing any constraints or adaptive feature to Assembly1, while Assembly2 replaced with Assembly3.
Assembly1.iam
- Assembly2.iam
+ Part1
+ Part2
This is what I want:
Assembly1.iam
- Assembly3.iam
- Assembly2.iam
+ Part1
+ Part2
But Assembly2 shouldn't lose any constraints to Assembly1.

One of the enhancements in 2013 is that users can send models to Showcase and convert constraints into animated behaviors, however, some users wonder if there is any way to select constraints which are within the subassemblies instead of the top assembly, how would you do it?
I have selected constraints in subassemblies but they don't become behaviors. The workflow allows users to select them, but they aren't converted into behaviors.

We have just upgraded to inventor 2012 from 2009. I had a simple .ipt created from a 3/8" grade 50 sheetmetal template in an assembly, and decided that it could be 1/4" grade 50. I originally went into the original part and changed the sheet metal default to 1/4". After returning to my assemble and performing a refresh it blew away all my constraints I had on the .ipt after the thickness change. I also tried doing a save as on the ipt then changing the thickness as a new part number and performing a replace component with the same results to my constraints. I've also noticed issues losing constraints by performing simple replace component commands on similar sizes of TS but just changing length. Has something happened to our templates during the migration to the new version of inventor? I don't remember ever having this many issues in 2009 when replacing components of similar geometry with just a different length or thickness.

This is probably a simple one that I am missing, but how do I get a parallel constraint applied to these two edges.

My need is to assembly parts into an assembly by a known position in the assembly. The part has a UCS and I create UCS on the assembly programatically. What I cannot do is to constrain the two UCS. I tried this (Inventor 2013 x64 on W7/W8 64, c++ 2010 by the way DEBUG mode is not working from the IDE):
CAssemblyComponentDefinition compDef = doc.get_ComponentDefinition();
// MOdules UCS
CUserCoordinateSystems coords = compDef.get_UserCoordinateSystems();
CTransientGeometry geom = m_InventorApp.get_TransientGeometry();
CMatrix matrix = geom.CreateMatrix();
[code]...

I have an assembly wherein one part is mated to another grounded part, with a face-to-face coincident mate. The click + drag type of movement appears to move the part, while continually solving this constraint.
However, it seems like there is no way to do a rotation in the same manner, where the constraint is continually updated. There appears to only be the "Free Rotate" command, which ignores the constraints.
Is there really no way to do this in Inventor? The application is that I am laying out a mold for many, many small parts, and I am trying to move and rotate them into position to get good packing efficiency and density. Each part will be attached to a mold base with one of the aforementioned face-to-face constraints, then slid & rotated around manually.
This seems like a really important piece of functionality. Solidworks can certainly do this, do a part rotation in an assembly, while solving for existing constraints.

I am using Autodesk Inventor Professional 2013.
Motor Model 1:1 is used to turn the wheel holders at various angles. The part named "front gear spring holder" is supposed to revolve and turn the inner part of the "front wheel holder" My problem is that I want to simulate the turning of the front wheel's using contact sets or 3d/2d contact sets in the dynamic simulation environment. I do not know how to do this, but I'm almost certain the program is capable of doing so. Also the spinning of the front wheels must be able to be done along with various angles of the front wheels(while turning, the front wheels must be able to still spin with the front gear spring holder".
I have seen threads and articles that say that making gears with contact sets is not recommended or possible but i have two instances here where they work perfectly fine using the dynamic simulation with 3d /contact sets. Take a look at the simulation I have saved as well.
I will need more on this assembly in the future, including how to create bevel gears that work at 90 degree angles or spur gears with contact sets instead of just simulating their movements .

I have a frame generator assembly that I created to take advantage of the frame analysis tools. This assembly was later broken down into the main fabricated assemblies (for drawing purposes) using the "demote frame generator component" tools. The basic question is this: can I take one of the "demoted" sub-assemblies and move it to another assembly file all-together?
best way to move the four legs from the platform assembly to the tank assembly after the fact? I was thinking I would just place the leg sub-assembly into the tank assembly and then delete it out of the platform one but I'm not sure of the ramifications.

I am working on a project which uses two gear reducers. I have built the gear reducer and saved it as an assembly file so to import it to the assembly of the project. When i import the reducer assembly into the project assembly, the reducer is shown as a single piece, not as a mechanism which i can interact with. But if i select, by doubleclicking, the reducer, it becomes active again. The problem is that i want to connect the reducer to another gear assembly and watch it interact.

I am trying to add an angle constraint to an assembly of a ladder design. I need for the ladder to be able to be set at an angle against a wall and not vertical. The ladder design is such that the base brackets are fixed to the ground and the rest of the ladder may move about the axis of the bolted connection at the base of the ladder. I cannot get the angle constraint on the ladder to allow this.

I got a problem with editing angle constraint in assemblies. I tried edit property of constraint but it didn't move model. Simply changing Angle attribute of constraint item don't work.
Only way I achieved movemenet is
if(oOccurrence.Constraints[i].Name.Equals(name))
{
AngleConstraint a = (AngleConstraint)oOccurrence.Constraints[i];
Object oEntity1 = a.EntityOne;
Object oEntity2 = a.EntityTwo;
String sVal = "" + angle + " deg";
[Code]...
but this is really slow, as much as changing throught parameter:
if (assemblyDoc.ComponentDefinition.Parameters[i].Name == "d655")
{
Inventor.Parameter invParam = assemblyDoc.ComponentDefinition.Parameters[i];
invParam.Value = Math.PI * angle/180;
inventorApplication.ActiveDocument.Update();
}

I created a general assembly (GA) and placed several parts and assemblies. After I realized there are too many parts and assemblies in the GA to reasonably place on a drawing. Now I want to remove some parts and create sub-assemblies. Is there an easy proceedure to select some parts in the GA and insert them into a new sub-assembly and (hopefully) keep the constraints intact?

I have a sub assembly with a sliding part in the main assembly but the sliding part is locked, the "flexible" option is greyed out?My head is not in gear this year yet! Am I able to move unconstrained parts in sub assemblies via the main assembly by pulling them with a mouse?

I have a sub assembly that I am making a drawing of. The assembly drawing needs to also display the main assembly as a reference part (in phantom lines). The sub assembly is made up of flexible hoses that need their connection points referenced.
Inserting the main assembly into the drawing, so that I can see both the main assembly and the sub assembly together, messes up the parts list and balloons.
There must be a way to dislay the sub assembly in the main assembly and still have the part list and ballons reference the sub assembly?

Is there a way to run a rule which is part of a sub assembly from the parent assembly?
I have a parent skeleton assembly containing many icopy assemblies. These subassemblies are based of one master assembly which in turn has a common part. (hence why I am using the icopy feature)
This standard part has an ilogic rule which varries the number of creases in a wall panel. eg. when the panel is 1200 wide there are 2 creases, when the panel is under 800 wide there is one crease and when the panel is less than 600 wide then there are no creases.
When I insert the icopy assembly into the master skeleton assembly and click select the widths of the panels they stretch and change to suit my skeleton. However I am having to visit each copied panel to run the crease rule.
Is there an operation or some sort of trigger I can implement to make this rule run as soon as the sub assembly is inserted?

I have an assembly that is nearly completed. I am trying to change the lengths of two side rails (arrow pointing to one of them). On each end of these rails are several components that have been constrained to the rails.
When I change the length of the rails, many of the constraints show errors. I expected that all components would move with the ends of the rails as they are shortened since that is where they were constrained, but this has not happened.
The constraint recovery tool has not been useful to me.

I've got a relatively simple assembly (attached) containing 3 iparts. I change the center component the assembly and I lose all the constraints. Only the length changes, I'm sure I did this before but yet it turns out to be an epic disaster.

Given the list of AssemblyConstraints how do I list them textually? For example
// error checking removed for brevityCComPtr<AssemblyConstraints> pConstraintList;pAssDef->get_Constraints(&pConstraintList) ; _tprintf_s (_T("The assembly has %d constraints
"),pConstraintList->Count);const int ikNum = pConstraintList->Count ;for (int iConstraint = 0 ; iConstraint < ikNum ; i++) { CComPtr<AssemblyConstraint> pConstraint; hr = pConstraintList->...
what to put here? how to print out more data here...? }How do I get each constraint from the list?

If I have two parts as occurrences in an assembly, how can I programatically constraint two workplanes (one from each part) to a flush constraint.
My problem is that I can get the Occurrences, say ...
CComPtr<ComponentOccurrence> pTube1Occ = ...
CComPtr<ComponentOccurrence> pTube2Occ = ...
...but I don't know how to delve into these two pointers to get hold of two named workplanes within them. I'd then pass the two workplanes (somehow?!) to the AddFlushConstraint function.
get_SurfaceBodies doesn't seem right and neither does get_SubOccurrences.

I have a linear slide assembly, for which I've set up limit constraints in the open and closed position.
It all works well, with one being able to drag the slide open and closed and the parts stopping in the correct positions.
I then inserted 4 of these assemblies as sub assemblies in a parent assembly.
I then constrain another part to the 4 slides.
I want to just drag on this part, to make the slides move to open positions.
This is to check kinematics etc.
One cant do this. You can only drag one slide open, by activating that slide in the model browser.
Any way to make limits work properly in upper assemblies?

When I record an animation in .avi using the Drive Constraint command here's what pops :
-The codec you selected to compress this AVI video stream cannot handle the current screen color depth and/or the graphics frame size. Please try another codec.
-Then I press OK and it records but the AVI file is empty and no video is watchable.
What can I do?

I have an assembly with multiple instances of a subassembly. I'd like to remove the subassembly and place the subassembly components (i.e. multiple instances) in the main assembly. When complete, the top assembly would have multiple instances of all the subassembly components.
Component promote seems like the right way to do this. So, I selected an instance of one of the subassemblies components and promoted it. That component was promoted, removing it from the subassembly as placing it in my top level assembly.
However, all the other instances of that component disappear (which makes sense since that component is no longer in the subassembly). Unfortunately, this means I have to assemble and constrain all the other instances that disappeared.

We have an issue regarding Parts Lists. We currently produce a 'master parts list drawing' for the jobs we produce. This drawing has 2 rolled up parts list on it -
1 - purchased parts - so buying can order all the required parts in one go.
2 - manufactured parts - so production know which and how many parts to make.
Both of these can be setup in Inventor (using filters) so they display only the correct parts from the BOM. However, neither of these show assembly / subassembly files (and consequently drawings). Is there any way of creating a parts list that can show assembly files only?
